Application ll'ed Beeernber To all whom if may concern:

Be itlniownthat LL Firestone L. Germania?, a citiaen et the United States, residing' at Cl'iicag'o, fin ithe `county o-' Coeli and State ot illinois, have invented a new andv iis-'etui improvement lfin Gas-Venting Devices, oit which the following is la specification.

hify invention relates, moreparticularly, to devices through which gas generated in a chamber, as, tor eXample,-'aileg,1in the production ott lcertain liquids, particular-ly through :termentatiom is vented.

As to one feature of my invention, it relates :to va novel' and simple construction of bung' :through which fthe gas yis permitted to escape 3` and as :to zainother :feature lit relates to I.the yconductingo'l `the gas away `'iii/"oni :the chamber, `While alioidingithe'entry off airfor other :fluid into the chamber and vwhich would contaminate :the contents thereof.

@ne oit 'my objects is tto` proiid'e a novel and simple construction 'of gras-ventingbung `which shall he `inlapted Lto` he positioned in bung' openings oihegrs and the flile, yoitdift'- ferent sizes and which shally effectively `opel1- late to Aserve Yasfa gas went in connection with thesefdiiiierentsizes ot receptacles, evenayhen the `latter are almostcompletely =iflld with theA 'liquid yunchargoingg` treatment. Another object is to iproyide a gas-'ventinghung which umay be 1driven `:into :position in the bung hele, Without, danger 'et fbie'aleing the gaseonducting tube associated therewith. Another object is to provide fa uiovel and simple construction of air-Venting,1 device whereby the :gas may 'readily7 tlow Atherethrougilr to'enhanst and by Which reverse how through the gasy passage will rbe pim Vented; `and other `objects :are to .generally improve rupon structures et the character aboyeu'elierred to. i

Refenring to ythe accompanying drawing, the tifrure therein illustrated is a View in lon-- gitudinel sectional elevation through the bungiopening portion of la barrel, `this bung` opening' being equipped with a gas-'venting device, alsovshowniin `sectionalielevation and' embodying im'y improvements.

The 1hung portion of the device `is represented at 2, this bung', which may he of uio-od or any other suitabie material, being` of trus tro-eonical form7 `as shown, -to seat in the tapered bung` opening' 3 shown as provided in the side Wall 4t et a keg containing' the fluid, represented at 5 and `trom which the to be conducted out of the keg is emite, ieee saranno. eeaeei.-

The bung '2 ,is shown las provided with aipassage v(5 extending :entirely lengthwise therethrough, the iower end `oi this jpassage opening` throuirh ithe Ybottom of `the bung, and the upper portion ot this :passage being; 4exfpanded Eto cause it to 'lare'outward-iy' as rei resented at 7, The bung fyalsocontains at its lower end a cross Vpassage -S intersecting the `passage 6 and opening atits opposite .ends `thi-ouah the side-ot thebung.

Codpei'ating with the bung 2 is 4a .gas Venting pipe @positioned at its `lower end in a stopper i0 shown as of trustro conical 'orrn and :preferably yformed of icork, `this stopper fitting' iinto the upwardly opening portion (fot) the passage iinthebnng. The upper end of lthe `tube 9 is turned down Wardl-y :to present the portion '1:1 which extends through a Irubber stopper l2 confined 4inithe `mouth iet' a bottle 13 Iintowthe interior of which latter @the lower open .end @of lthe `portionll of fthe tube opens.` 'llhe stopper 12' is provided with a vent-opening ld,1and i the lower open end ot the portion Il oft ithe tube cooperates with, a Heat 'l5 shown as termed of a Vgenerhill-y `siiherical lower end portion d'6 aand an' upwartllyeentending: shank portionY l@ taperingi upwardlypat which pol'- tion it extends into the lower end oif=theip`ortion ill the 'tuheythe ihottle icontaining any suitable liquid, as, tor example, water, represented at E18 Which extends above the lowerfopenend of the Vpoition rlib-orltheftube. .Assuming :the .gas wentingj `device to be pp'lied to :a heg inthe position :shown in Jthe -(lra\yin'gs,the rgas generated iby the iterwr inenting liquid 5 "rises through the passage G in the bung` andthrongh the pipe 9, Las 'tor example `of aluminum or glass, discharging' from the 'lowerend otitheiportion ll thereof into the Water 18 'and thence passing outA Wardly to the atmosphere 'through the `vent 14: in the stopper d2, 1the gas, in its moye- Inent forcing the" check-valve l5 `downwardly against the buoying action oil' the liquid 18.' lnasmuchas the liquid'lrS exerts a buoying' action on the yalfye 115, bac'lesiphoning vof `the liquid 18 into the tube 9 `is vpositively pre vented should the pressure in the keg' above the level fo'tthe liquid 5 for any reason become reduced below atmospheric @pressure The provision of the device in separable parts permits the stopper equipped tube E) to he preiiminarily disconnected from the hung' 2' which latter may then be driven into the bung hole 3 by vstriking it with 2 1,5se,ees

the desired force, thereby eliminating any danger of breaking the tube leading frein the bung, and when the stopper l0 is inserted into the bung tight lit is insured by reason of the resilient character of the stop- The feature of providing the gas vent with two outlets one of which extends through the bottom of the bung and the other through the side of the bung, is of advantage particularly in connection with the use of the bung with bung holes of different sizes. rlhe bung 2 is shown in connection with a bung hole of relatively large size in which Case the lateral outlets of the Oas passage in the bung extend close to the under surface of the wall of the keg in which the bung hole is located, thereby providing for the passage of the gas into the bung even when the level of the fluid 5 therein extends to a relatively great height and covers the inlet opening throughthe lower end of the bung. lVhere the bung is used in a bung hole which is of relatively small diameter, the lower surface of the bung` would extend considerably higher than it does in the arrangement shown, even to such a height that the lateral inlets would be covered by the wall of the bung hole 3, and the gas would be conducted from the space above the fluid 5 into the gas inlet opening through the bottom of the bung. rThe bung is thus adapted for use in connection with bung holes of different diameters, even where the top of the fluid 5 extends closely adjacent to the under surface of the wall in which the opening 3 is located.

Furthermore it will be noted that the va` rious parts of the device are rendered adiustable relative to each other to accommodate the latter to the various conditions met in practice, and that these parts may be readily disassembled, in which condition they occupy very small space, which is of particular advantage in shipping and storing, and may be readily assembled for use.

The feature of providing the stopper l2 is of especial advantage particularly as compared with the screw cap commonly provided, in that assembly of the bottle and stopper may be readily effected by merely pressing these parts toward each other and a highly effective closure results rlhe stem of the valve l5 is niade relatively long, as shown, 1n order thatrit will not fall out of the tube when no water is in the bottle 18.

rlhe feature of providing the separable bung and stopper is of further advantage in that the stopper l() is adapted to be fitted into the mouths of different sized bottles, as for enample from pint to live gallon bottles, and thus by separating the bung from the stopper l0, the gas-venting device may be used with such bottles, whereby the device is adapted for application to l-:egs and bottles of different sizes.

l.lilhile l have illustrated and described a particular construction embodying my invention, l do not wish to be understood intending to limit it thereto as the saine may be variously modilied and altered without departing from the spirit of the invention. i

lllhat l claim as new, and desire to secure by Letters Patent, is:
